Marantz SA11S3

rsfphil:

Congratulations on the new Marantz player . Owning three Marantz SACD players, I also like the Marantz "sound". To take your player to a higher level consider replacing the main power fuse with a Synergistic Research "BLACK "brand fuse. I heard I significant improvement in sound with the upgraded fuse.

Enjoy your new system.

Before you start auditioning - changing cables I do suggest replacing the main fuse on the Marantz with a Synergistic Research "Black" fuse. 

This upgrade has improved the sound of my three Marantz players! They are sold with a 30 return policy. There is a long thread in the Amplifier forum with the positive results of these fuses.

There are seven fuses in the Marantz SA11-S2.
All are small -slow blow. 
All are inside the Player'
So you have to remove the top lid to replace the fuses.
At the back of the player there are 3 screws along the top edge. Remove screws. Slide the lid back about 1/2 inch. It will not want to slide towards the back. You will have to use a thin flat screwdriver to pry it backwards. You will feel it loosen and then you can lift it straight up and off.

Main fuse on is on far left side (looking from front of player) -2.5 amp. Substitute a 3 amp fuse.
There are six rail fuses to various sub circuits.
Two are 1.6 amp
One is 1.25amp
Three are 1 amp

I suggest using 1.6 amp fuses in these locations.
The main power fuse has the greatest single effect.
The other six fuses do add additional improvement.

Yes it is fascinating that the right fuse can have a significant effect on the sound, but it does. I believe you will be very happy with putting in a Synergistic Research "Black" fuse.

I think you will be quite happy putting in a Synergistic Research Black fuse in your Marantz. Leave your unit on 24/7. After about 100 hrs, the unit will really sound good.

As an added bonus the Synergistic Research fuses are sold with a thirty day return policy!

Enjoy that fabulous Marantz sound.

The Marantz SA11-S1 does not have a user replaceable main power fuse. It is hardwired into the circuit. It does have a total of 5 rail fuses that go to each subsection of the player. The player sounds better with these fuses upgraded. You can replace them one at a time.

Your Marantz will sound better if always left on. The DAC chip - circuit takes a long time to 100% stabilize. Antelope brand DAC's used in the recording studio are always left on, as even a broken in unit will take three days to stabilize.

Marantz equipment responds very well to fuse upgrades, especially to the Synergistic Research Black fuse. The system improvement I believe from this fuse is greater than going to balanced cables. Been there - prefer unbalanced in my Marantz systems.

If any Marantz users are still using regular home construction wall outlets, I hope you will try either the Furutech GTX-R outlet or the Synergistic Research Teslaplex SE outlet. Both will allow the Marantz players and amps to reach their full sonic potential. The Synergistic Research outlets are less costly and sold with a thirty day money back trial.

Marantz makes some great equipment - enjoy.

That is one approach that works to move the lid back the 1/2 inch and then lift it up and off.

I hope the Marantz readers of this thread will try a Synergistic Research Black fuse at the main fuse location. The sonic improvement is worth the effort to get that darn lid off.
